Trailer for Dungeons and Dragons: The Book of Vile Darkness

Yes, there is a third Dungeons and Dragons movie. No, it's not a fan-made film, it's actually a made-for-TV movie that was supposed to air on Syfy but was delayed, probably because... well, look at it. If this movie really was delayed for quality reasons though, that means it must be far worse than what the trailer shows. How do you make a movie too bad for the channel that green-lit Sharktopus?
